Does's it possible to use where clause for more than one feature type?
f.e. [gas_distribution]cp_bond_wire where id > 0; [gas_distribution]cp_rectifier where id > 0
Two where clause delimited with ";".

No, as each feature type has its one data stream
or you can first use the Reader option (Single Merged Feature Type), then set the Where Clause: id>0
I have found two solutions for me:
First one: use union between sql commands
>gas_distribution]cp_bond_wire where id > 0 union gas_distribution]cp_rectifier where id > 0
Second one:
Prepare "Alternative" with specific feature types in Smallworld and use it in SMWD Reader
Take care.

This is not solution, because SMWD Reader reads all teature types and after that apply the where clause to all data. I want to read just specific Feature types from all that are provided by SmallWorld on his port. O have foumd solutions described bellow.
Thanks for reply ...

The second method is a bit tedious if you'll implement it, you have to create the Alternative in SW then back to FME, to read from.
But, if the first method worked, then definitely it's the answer.
The first solution is good just for few feature types ... In case of more than 10 f.t. it takes a long time to read all data.

I see, absolutely, reading bulk data from multiple feature types in Smallworld is a very slow process.
